in the moment that you turn on power rails in a gradient, they turn to the other side
another bug: the animation of a exploding TNT is not coordinated with the effect and the sound (looks like when you are in a lag server)
and finally, 2 minecarts can not be put in a same rail, this is unconfortable because this is used for minecart cannons and explosives

Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
And please use the search function in the future as all of the issues are reported multiple times.
Powered rails = MC-60152
TNT = MC-59904
As for the Minecarts not stacking, it appears to be a WAI, as Minecarts with TNT no longer stack.
